ATTACHMENT OF KEYS TO CANS. 7

Application filed December 4, 1924, Serial No. 753,766. Renewed July 11, 1928.

This invent-ion relates to the attachment to tearing strip cans of keys for engagement with the tongue to remove part of the can set off by score lines, and has for its object broadly the provision of an improved attachment of the key in various positions to prevent loss and to facilitate the easy separation of the key from the can for use.

An important object of the invention is the provision of a key which may be easily attached to a can, which may likewise be easily removed from the can, and which should the occasion arise, may be readily reattached thereto withoutthe use of tools, soldering or welding, thus effecting a material saving in the original assembly cost, a secure fastening means and permitting reattachment by the user upon occasion to prevent the loss thereof. Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which taken in connection with the accompanying drawings, discloses apreferred embodiment thereof.

Referring to the drawing:

Fig. 1 is a partial perspective view of a can and key attached thereto in accordance with .my present invention.

Fig. 2 is a section taken substantially on line 22 of Fig. 1.

Fig. 3 is a perspective view with parts broken away and of a slightly different embodiment of the invention.

Fig. 1 is a section taken substantially on line 44 of Fig. 3.

Fig. 5 is a perspective view with parts broken away and showing a second. slightly different embodiment,

Fig. 6 is a section'taken substantially on line 66 of Fig. 5.

For the purpose of illustrating my invention, I have shown a can body 11 provided with encircling score lines 12 providing a tear strip between them terminating in a tongue 13 and provided with an end closure 14-, which in the present instance, is sgcured thereto by means of the usual double seamed or interfolded flanges 15.

It will, of course, be readily apparent as the invention is better understood that the particular structure of the can and the shape I and location of the portion to be removed by the key are utterly unimportant from the standpoint of the present invention.

I provide a key which consists of a. piece of position outside and along the wall of the cover of the can, or as in Fig. 5, positioned on the outside and alongside of the wall of the can, theend 21 of the key is die formed in accordance with the desiredposition and with the contour of the seam to which it is desired to secure the key, as shown at 23, Figs. 2 and 6, the portion 24 thereof having sufficient flexmg strength to secure the key in position. When it is desired to attach the key in the can as shown in Fig. 3, the handle 16 is die formed in accordance with the contour of the seam to which it is desired to secure the key as shown at 25 Fig. 4, the portion 26 thereof having sufiicient flexing strength to secure the key in fixed position. The key is applied toa can by snapping into position over the seam. To remove the key, it is only necessary to lift outwardly or upwardly on the free end of the key, causing it to disengage as will be readily apparent. It is to be noted that the key is in no way harmed by the removal thereof, and that it may be reapplied to the can if desired.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and

it will be apparent that various changes may be made in the form, construction and ar-' rangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material advantages, the

forms hereinbefore described being merely a move said portion to open said can, and a key having a slot for engaglng said tongue,

said key having an end bent to detachably embrace the seam of said can so that the key can be detached from the seam and applied to said tongue.

3. A tearing strip container having an end seam, and a key having a slot for receiving said tearing strip for opening said container, the said key having one of its extremities formed into a flexible clamp which is adapt ed to releasably snap over said end seam, to securely hold the key during transportation and to release the same for the opening opera- 15 tion.

4. A key for opening double seamed containers, comprising a handle part, a body part said body part terminating into a flattened end formed into a flexible clamp and adapted to be snapped over a double seam of said container and because of its'fleiging strength to be released therefrom for the opening operation.

- 5. A key for opening double seamed containers, comprising a handle part, a body part, the end of said handle part eing formed into a flexible clamp and adapted to be snapped over a double seam of said container and because of its flexible strength to be released therefrom for the opening operation.
